Is Alfredo sauce Low FODMAP?
Alfredo sauce is high FODMAP. It's best avoided during the elimination phase.
Serving thresholds
| Serving | FODMAP level | Data quality |
|---|---|---|
| ½ cup (125 g) | High | Class rule |
Thresholds are per sitting. FODMAP load stacks across a meal — two “low” servings of different foods can still add up.
Which FODMAPs are in alfredo sauce?
During reintroduction, test the groups above one at a time — tolerating alfredo sauce depends on your personal threshold for Lactose, Fructans, not on the food itself.
Good to know
Alfredo combines cream and parmesan with butter and garlic — high in lactose and fructans at one pasta serve.
Where these numbers come from
- Derivation note: Cream + butter + parmesan + garlic; lactose load from cream and fructan load from garlic both above cutoffs at one pasta-portion serve.
- Peer-reviewed paper: Varney J et al. (2017) FODMAPs: food composition, defining cutoff values and international application. J Gastroenterol Hepatol 32(S1):53–61.
Phase derives serving thresholds from published research and food-composition data so every number is auditable.
